Further, in one traffic signal device, changing from lighting of a red lamp to lighting of a blue lamp is called “changing from a red signal to a blue signal”.

  FIG. 1 is a block diagram of a driving support apparatus 1 in the present embodiment. The driving support device 1 includes a driving support management information storage unit 11, a receiving unit 12, a driving support content information acquisition unit 13, and a driving support unit 14.

  The driving support management information storage unit 11 stores one or more driving support management information having a driving support start condition that is a condition for starting driving support and driving support content information indicating the content of driving support. . That is, the driving support management information is information used when driving support while the mobile body is traveling.

  The driving support start condition is a condition related to the traffic signal status. That is, the driving support start condition is a condition having traffic signal status information. In addition, the driving support start condition includes, for example, a condition related to the time until the moving object arrives at one traffic signal, a condition related to the distance from the moving object to the one traffic signal, and a condition related to the speed of the moving object. It may be. The “arriving” means, for example, arriving immediately below the traffic signal or arriving at a point within n meters from the traffic signal. The driving support start conditions are, for example, “the traffic signal is a red signal”, “the traffic signal is a red signal when passing”, “the latest traffic signal is a red signal, and the time until the traffic light changes to a green signal is 30 It is “seconds”, “the time until the latest traffic signal changes from a green signal to a yellow signal is 20 seconds, and the time until it arrives at the traffic signal is 10 seconds”, and the like.

  Further, the driving support content information is specifically information indicating the control content performed on the moving body for driving support. The driving support content information includes, for example, (1) increasing / decreasing attributes of the moving body when traveling, (2) switching ON / OFF of the operation of the moving body, and (3) operation of the device included in the moving body. This is information indicating that it is adjusted. The “property during travel” in (1) is, for example, speed or acceleration. In addition, the “operation of the moving body” in (2) is, for example, idling or lighting of a direction indicator. The “device” in (3) is, for example, a brake, an engine, a handle, a gear box, and the like. Further, the driving support content information may be a program for performing these controls or an identifier for identifying the program. When the driving support content information is an identifier of a program, the program identified by the identifier is usually stored in the driving support management information storage unit 11.

  In addition, the driving support start condition may have a condition related to the state of the moving object. That is, the driving support start condition may have a condition having driving support content information.

  The receiving unit 12 receives one or more pieces of traffic signal information that is information related to traffic signals. In the present embodiment, the traffic signal usually transmits one traffic signal information corresponding to the traffic signal per traffic signal. Therefore, the receiving unit 12 normally receives the transmitted traffic signal information from each of the one or more traffic signals, and receives a total of one or more traffic signal information.

  In addition, the receiving unit 12 receives one or more traffic signal information from one or more traffic signals that are usually located on the road on which the moving object is traveling and are located in the traveling direction of the moving object. The “traveling direction of the moving body” is usually a range of 90 ° to the left and right from the direction in which the moving body is facing. At this time, it is preferable that the receiving unit 12 receives one traffic signal from one traffic signal closest to the current position. The “most recent traffic signal” is a traffic signal located at the nearest position among one or more traffic signals located on the road on which the vehicle is running. In addition, the reception unit 12 may include one or more traffic signal information from one or more traffic signals located within a predetermined distance range (for example, within a radius of n kilometers from the current position) from the current position of the mobile object. May be received.

  The receiving unit 12 may be, for example, a device corresponding to one traffic signal, and may receive traffic signal information from a device that transmits one traffic signal information corresponding to the traffic signal. The device is, for example, a radio beacon or an optical beacon.

  The driving support content information acquisition unit 13 acquires from the driving support management information storage unit 11 driving support content information corresponding to the driving support start condition that matches the traffic signal status information included in the traffic signal information received by the receiving unit 12. . The driving support content information acquisition unit 13 includes, for example, driving that the traffic signal status information included in the traffic signal information received by the receiving unit 12 has in one or more driving support management information stored in the driving support management information storage unit 11. Determine which of the support start conditions is met. And the driving assistance content information acquisition part 13 acquires the driving assistance content information corresponding to the said matching driving assistance start condition from the said driving assistance management information. The “acquisition” includes a jump of the program pointer to the program indicated by the driving support content information.

  For example, it is assumed that the traffic signal status information included in one traffic signal information received by the receiving unit 12 is “red”. The traffic signal information means “red signal”. Further, it is assumed that the driving support start condition is “red”. The driving support start condition means “red signal”. In this case, the driving support content information acquisition unit 13 determines that the traffic signal status information matches the driving support start condition, and acquires a route condition corresponding to the driving support start condition.

  For example, it is assumed that the traffic signal status information included in one traffic signal information received by the receiving unit 12 is “red = 30 seconds”. The traffic signal information means that “the time when the red signal is present is 30 seconds remaining”. Further, it is assumed that the driving support start condition is “red ≦ 30 seconds”. The driving support start condition means “the time when the signal is red is remaining 30 seconds or less”. In this case, the driving support content information acquisition unit 13 determines that the traffic signal status information matches the driving support start condition, and acquires a route condition corresponding to the driving support start condition.

  Further, for example, it is assumed that the traffic signal status information included in one traffic signal information received by the receiving unit 12 is “red = 40 seconds”. In addition, it is assumed that the scheduled time (hereinafter, estimated arrival time) until the mobile object arrives at the traffic signal is “20 seconds”. For the calculation of the scheduled time, the speed of the moving body and the distance from the current position of the moving body to the traffic signal are usually used. Moreover, the speed of the said mobile body and the distance from the present position of a mobile body to a traffic signal are normally acquired by the driving assistance content information acquisition part 13. FIG. Since methods and procedures such as acquisition of the speed of the moving object, acquisition of the distance from the current position of the moving object to the traffic signal, and calculation of time using the speed and distance are known, detailed information is provided. Description is omitted. The driving support start condition is “arrival time: red signal”. The driving support start condition means “when the mobile object arrives a red signal”. In such a case, since the moving body arrives at the traffic signal while the traffic signal corresponding to the traffic signal status information is a red signal, the driving support content information acquisition unit 13 has the moving body at the traffic signal. When arriving, the traffic signal is determined to be red. Then, the driving support content information acquisition unit 13 determines that the traffic signal status information and the estimated arrival time match the driving support start condition, and acquires a route condition corresponding to the driving support start condition.

  Moreover, the driving assistance content information acquisition part 13 usually acquires one driving assistance content information. For example, when the traffic signal status information included in one traffic signal information received by the receiving unit 12 matches two or more driving support start conditions, the driving support content information acquisition unit 13 follows, for example, a predetermined criterion. One driving support start condition is determined from the two or more driving support start conditions, and driving support content information corresponding to the driving support start condition is acquired. Note that the “predetermined criterion” is, for example, matching first, matching last, date being the latest, and the like. In addition, when the said reference | standard is not decided beforehand, the driving assistance content information acquisition part 13 may acquire 2 or more driving assistance content information.

  The receiving unit 12 is usually located on the road on which the moving body is traveling, is located in the traveling direction of the moving body, and is one traffic signal information from the nearest traffic signal. Is preferably received. Therefore, the driving support content information acquisition unit 13 normally uses the traffic signal status information included in the one traffic signal information as a target for determining whether or not one or more driving support start conditions are met.

  The driving support unit 14 performs driving support of the content indicated by the driving support content information acquired by the driving support content information acquisition unit 13. For example, it is assumed that the driving support content information acquired by the driving support content information acquisition unit 13 is “speed ≦ 20 km / h”. The driving assistance content information is speed control information indicating that the speed is controlled. The speed control information means that the speed of the moving body is set to 20 km / h or less. In this case, the driving support unit 14 controls the speed of the moving body so that the speed of the moving body is 20 km / h or less. The speed control includes, for example, applying a brake, reducing an accelerator depression amount, and reducing an engine speed. In this way, when the driving support content information is information indicating concept control during traveling of the mobile body such as speed, the driving support unit 14 is usually a device provided in the mobile body, and the mobile body travels. Control the equipment related to

  Further, for example, it is assumed that the driving support content information acquired by the driving support content information acquisition unit 13 is “brake: 80%”. The driving assistance content information is brake control information indicating that the brake is controlled. Further, the brake control information means that the brake of the moving body is applied with the depression amount of 80% of the whole. In this case, the driving support unit 14 controls the brake of the moving body so that the depression amount of the brake becomes 80% of the whole.

  Further, for example, it is assumed that the driving support content information acquired by the driving support content information acquisition unit 13 is “idling: OFF”. The driving assistance content information is idling control information indicating that idling is controlled. Further, the idling control information means that idling is turned off. In this case, the driving support unit 14 stops the engine in order to turn off idling.

  For example, when the driving support content information acquired by the driving support content information acquisition unit 13 is a program or an identifier of the program, the driving support unit 14 selects the program or a program identified by the identifier of the program. Run.

  The driving support management information storage unit 11 is preferably a nonvolatile recording medium, but can also be realized by a volatile recording medium.

  The receiving unit 12 is usually realized by a wireless or wired communication means, but may be realized by a means for receiving a broadcast.

  In addition, the driving assistance content information acquisition unit 13 can usually be realized by an MPU, a memory, or the like. The processing procedure of the driving assistance content information acquisition unit 13 is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit). The driving support content information acquisition unit 13 may be realized by a so-called vehicle speed sensor, a speed sensor, a satellite navigation system (such as a GPS receiver), or a device that receives position information from a mobile communication base station. Good. Further, the processing procedure of the driving support content information acquisition unit 13 is usually realized by software, and the software is recorded in a recording medium such as a ROM.

Next, a specific example of the operation of the driving support device 1 will be described. In this specific example, it is assumed that the driving support device 1 is an electronic control unit (hereinafter referred to as ECU) mounted on a vehicle. Moreover, the receiving part 12 shall receive 1 or more traffic signal information during driving | running | working of a motor vehicle. That is, it is assumed that the receiving unit 12 starts receiving one or more traffic signal information when the automobile starts running. Moreover, a traffic signal shall transmit the traffic signal information of the said traffic signal with respect to the mobile body within the range of the predetermined distance. That is, the receiving part 12 shall receive the traffic signal information of the said traffic signal, when approaching to the predetermined distance with respect to one traffic signal. The predetermined distance is different for each traffic signal. Further, it is assumed that the driving support management information storage unit 11 stores the driving support management information shown in FIG. The driving support management information includes an ID (item name: ID) for uniquely identifying each record, a driving support start condition (item name: start condition), and driving support content information (item name: support content). Have

  First, it is assumed that a driver (user) starts an automobile engine and starts driving. Then, the car starts running. Moreover, the receiving part 12 starts reception of traffic signal information. At this time, it is assumed that the receiving unit 12 has not received traffic signal information.

  Here, it is assumed that there is a traffic signal that transmits traffic signal information to a moving body that is located on a road on which an automobile is traveling and passes a position 300 m from the position. In addition, it is assumed that the car passes through a position 300 m from the traffic signal. Then, the receiving part 12 receives the traffic signal information which the said traffic signal is transmitting. Here, it is assumed that the receiving unit 12 has received traffic signal information having traffic signal status information “blue → red: 15 seconds”. The traffic signal status information means that the time from a green signal to a red signal is 15 seconds.

  Next, the driving assistance content information acquisition unit 13 calculates a scheduled time until the vehicle arrives at the traffic signal from the current position. Here, it is assumed that the estimated arrival time is “20 seconds”. Then, the driving assistance content information acquisition unit 13 determines that the traffic signal is a red signal when the automobile arrives at the traffic signal.

  Next, based on the above determination result, the driving support content information acquisition unit 13 receives the traffic signal status information “blue⇒red: 15 seconds” received by the receiving unit 12 as “ID = 012” in FIG. It is determined that the start condition “(arrival time: red)” is met. The driving support start condition means that a red signal is generated when the mobile object arrives. Then, the driving assistance content information acquisition unit 13 acquires the driving assistance content information “speed ≦ 10 km / h” of the “ID = 012”. The traffic support content information means that the speed of the moving body is 10 km / h or less.

  Next, the driving support unit 14 controls the speed of the car so that the speed of the car becomes 10 km / h or less according to the driving support content information “speed ≦ 10 km / h” acquired by the driving support content information acquiring unit 13. To do. At this time, the driving support unit 14 transmits, for example, an electric signal indicating that the accelerator is turned off to the accelerator. Moreover, the driving assistance part 14 transmits the electric signal which shows applying a brake to a brake, for example.

  Further, for example, it is assumed that there is a traffic signal that transmits traffic signal information to a moving body that is located on a road on which an automobile is traveling and passes a position 800 m from the position. In addition, it is assumed that the automobile passes through a position 800 m from the traffic signal. Then, the receiving part 12 receives the traffic signal information which the said traffic signal is transmitting. Here, it is assumed that the receiving unit 12 has received traffic signal information having traffic signal status information “red: 50 seconds”. The traffic signal status information means that the remaining red light time is 50 seconds. At this time, it is assumed that the driving assistance content information acquisition unit 13 calculates the estimated time until the vehicle arrives at the traffic signal from the current position, and calculates the estimated arrival time “15 seconds”.

  Next, the driving assistance content information acquisition unit 13 determines the traffic signal status information “red: 50 seconds” received by the reception unit 12 and the scheduled time until arrival at the traffic signal “ID = 014” in FIG. Is determined to satisfy the driving support start condition “(40 seconds ≦ red <60 seconds) & (5 seconds ≦ arrival <20 seconds)”. The driving support start condition means that the remaining red time is 40 seconds or more and less than 60 seconds, and the time from the current position to reach the traffic signal is 5 seconds or more and less than 20 seconds. . Then, the driving assistance content information acquisition unit 13 acquires the driving assistance content information “Brake: 40%” of the “ID = 014”. The traffic support content information means that the brake of the moving body is applied with a depression amount of 40% of the whole.

  Next, the driving support unit 14 controls the brake according to the driving support content information “brake: 40%” acquired by the driving support content information acquisition unit 13 so that the brake depression amount is 40% of the total. Specifically, the driving support unit 14 transmits to the brake an electric signal that makes the amount of depression of the brake 40% of the whole.

  In addition, for example, it is assumed that there is a traffic signal device that transmits traffic signal information to a moving body that is located on a road on which an automobile is traveling and is traveling from the position to a position of 50 m. In addition, it is assumed that the car stops at a position 30 m from the traffic signal. Then, the receiving part 12 receives the traffic signal information which the said traffic signal is transmitting. Here, it is assumed that the receiving unit 12 has received traffic signal information having traffic signal status information “red: 60 seconds”. At this time, it is assumed that the driving assistance content information acquisition unit 13 acquires the speed of the automobile and acquires the speed “0 km / h”.

  Next, the driving assistance content information acquisition unit 13 has the traffic signal status information “red: 60 seconds” received by the reception unit 12 and the acquired speed “0 km / h” of “ID = 015” in FIG. 3. It is determined that the driving support start condition “(red ≧ 30 seconds) & (speed = 0 km / h)” is met. And the driving assistance content information acquisition part 13 acquires the driving assistance content information "idling stop" of the said "ID = 015". The traffic support content information means that idling is stopped.

  Next, the driving support unit 14 stops idling in accordance with the driving support content information “idling stop” acquired by the driving support content information acquiring unit 13.
